1800E mixture lean over 3000rpm 1800

Have you done any sort of testing of the throttle position switch? It sounds like it’s triggering the idle position OK as you say the idle mixture screw on the ECU is effective. However it might not be making good contact at the higher (full throttle) position. It also needs to make-and-break the 19 times as you advance the throttle plate open.
